摘要:
A micro-LED macro transfer method, a micro-LED display device, and a method for fabricating the same are provided. In the micro-LED macro transfer method, the LED chips on an array are divided into a first plurality of LED chips and a second plurality of LED chips. An LED chip includes a first surface and a second surface. The first plurality of LED chips are configured so that their first surfaces are coupled to the first transfer substrate. The second plurality of LED chips are configured so that their second surfaces are coupled to the second transfer substrate. Accordingly, the first transfer substrate transfers the first plurality of LED chips to the first transfer substrate while the second transfer substrate transfers the second plurality of LED chips to the second transfer substrate.
